TRACK FOR DOOR RANGERS.

Application filed .Tune 25, 1928i. Serial No. 288,233.

My invention relates to new and useful improvements in track fordoor-hangers of the type comprising a plurality of trackforming sectionssupported in operative position adjacent the top of the door-frame inlongitudinal alinement with each other, by means of brackets connectedwith the doorframe, and is fully described and explained in thespecification and shown in the accompanying drawing, in Which- Figure 1is a view in elevation of my improved track.

Figure 2 is an enlarged view in elevation of two adjacent alinedsections of the track together with the bracket at the jointtherebetween, portions of said sections being broken away between theirends.

Figure 3 is a section taken at the line 3 on Fig. 2 and viewed in thedirection of the arrow.

Figure i is a section taken at the line 4 on Fig. 2 and viewed in thedirection of the arrow.

Figure 5 is a rear view of the structure shown in Fig. 4.

Figure 6 is a plan sectional view of a portion of the top member of adoor-frame showing it as equipped with my improved track of which twoadjacent alined sections only with a bracket at the joint therebetween,are shown, portions of these sections being broken away between theirends and the bracket being shown partly in section.

Figure 7 is a section taken at the irregular line 7-7 on Fig. 3 andviewed in the direction of the arrows; and v Figure 8, a perspectiveview of a key for locking together the adjacent ends of thetrack-sections.

In the arrangement shown 9 represents sections of a hollow cylindricaltrack, these sections being longitudinally alined to form a continuoustrack. Each section 9 is open at its bottom to form a slot 10, the slotsof the several sections 9 being longitudinally alined. The sect-ions 9are of a type adapted to receive within them door-hangers (not shown)the rollers of which extend into the interior of the sections and runalong their lower portions, and projecting port-ions of which hangersextend downward through the slots 10 to engage the door which theysupport.

Disposed at intervals along the track at the joints between the sections9 are supporting brackets 11 for attachment to the top of the door-frameand with the aid of which the sections 9 are assembled into a completetrack. The ends of the track may be supported from the door-frame in anysuitable way, as by brackets like the brackets'll, and where thesections 9 are of such length that support thereof intermediate theirends is necessary or desirable, supporting brackets may be provided atsuch locations.

The brackets 9 are each formed of two sections 12 and 13 which overlapthe joint between adjacent sections 9, the section 12 being shown asformed with a rear face 1li` at which it flatwise bears against the faceof the top-member 15 of the door-frame. The bracket-section 12 containsin its upper end a vertically elongated slot 16 to receive a fasteningdevice, hereinafter referred to, the front face of this bracket-sectionbeing shaped to present an outwardly-facing concave seatA 17 for therear portions of the track-sections 9, the section 12 adjacent the upperedge of the concave seat 17 being beveled, as represented at 18.

The front bracket-section 13 is formed, at its upper end, with anupwardly-extending plate-portion 19 at 'which it bears fiatwise againstthe face of the upper portion of the section 12, the portion 19 beingapertured, as represented at 20 to receive the fastening deviceherenbefore referred to and represented at 21, this device being in theform of a bolt passing through the aperture 21, slot 16 and an aperture22 in the framemember 15.

The lower end of the bracket-section 13 is forwardly deflected as shownand presents a rearwardly-facing concave seat 23 bearing against thefront portions of the adjacent sections 9, the rear face of the portionof the section 13 adjacent the upper extremity of the seat 23 andrepresented at 24C, being so disposed as to fit flatwise against thesurface 18 of the section 12.

The section 13 at its portion 24 and the section 12 at its portion 18contain alined apertures to receive bolts 25, which, together with thebolt 21, rigidly hold the bracketsections tightly clamped against thetracksections 9.

Each track-section 9 contains at points set in from its ends twoapertures 26 shown as slots with their long dimensions extendingcrosswise of the axes of the sections 9, these apertures being providedto receive at the joint between adjacent sections a key 27 shown as inthe form of a yoke the crosspiece 28 of which spans the joint betweenthe sections 9 and the legs 29 of which extend into, and closely fit,the apertures 26, the key 27 serving to lock the sections 9 againstrelative rotation and relative longitudinal movement.

The apertures 26, are so disposed that when longitudinally alined toreceive the key, the slots l0 in the sections 9 will be in alinement, asshown. By providing each section with a plurality of apertures in eachend, as shown, the provision of alternate sections 9 with slots 10dissimilarly arranged relative to the slots in the sections with whichthey alternate is'rendered unnecessary with the Vmanifest advantage. f

The keys 27 project beyond the outer sur 'faces of the sections 9 andVthus form projections to receive which the inner concave seat 23 ofsection 13 is recessed as represented at 30, this recess beingpreferably of such size and shape, as shown, that the key substantiallyclosely fits it, whereby van interlock is presented between the bracketand the adjacent sections 9 preventing rotation of the sections 9 in thebracket and the shifting of these sections lengthwise therein. By thisconstruction all of thesections 9 are held in mutual alinement by theconnections therebetween and with slots 10 in the desired position toaccommodate the door-hangers. Thus a firm and substantial trackconstruction is afforded which can be readily assembled and which can bemade entirely devoid of projecting brackets, which is of particularadvantage in packing and shipping.

Furthermore by employing the key-connections as described, the bracketsare devoid of projections for holding the track-sections againstlongitudinal movement or rotation, with the manifest advantage. y

While I have illustrated and described a particular construction emboding my invention, I do not wish to he un erstood as intending to limitit thereto as the same may be variously modified and altered withoutdeparting from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

1. In a sectional door-hanger track, the combination of a series ofaligned track sections, supporting brackets located at the jointsbetween said sections and each formed of separate sections between whichsaid track sections are clamped, means holding said bracket sections inposition about said track sections, and members projecting from saidtrack sections beyond the side surfaces of the latter, said bracketscontaining recesses to receive said members for interlock therewith inthe clamping of said bracket sections to said track sections.

2. In a sectional door-hanger track, the combination of a series of.aligned .track sections, a supporting bracket located at the joint ofsaid track sections and formed of separate sections between which saidtrack sections are clamped, means holding said bracket sections inclamping position about said track sections, and means for interlockingsaid track sections with said bracket comprising interlocking portionson said bracket and track sections adapted to become relativelypositioned for interlocking upon assembling said bracket sections withsaid track sections.

3. In a sectional door-hanger track, the combination of a series ofaligned track sections, a supporting bracket located at the joint ofsaid sections and formed of separate sections between which said tracksections are clamped, means holding said bracket sections in positionabout said track sections, and a member projecting from said tracksections beyond the side surfaces of the latter, said bracket containinga recess to receive said member to interlock therewith in the clampingof said bracket sections to said track sections.

4. In a sectional door-hanger track, the combination of a series ofaligned cylindrical hollow track sections slotted for the passage of adoor-hanger, a supporting bracket located at the joint of said tracksections and formed of separate sections adapted to clamp said tracksections between them, fastening means securing said bracket sectionstogether, and means comprising interlocking portions which interlocksaid track sections with said bracket sections against relative rotationof said track sections upon the assembling of said bracket sections andsaid track sections, said interlocking portions closely tting each otherand so disposed as to interiit in the relative movement of said bracketsections into clamping position.y i

5. In a sectional door-hanger track, the combination of a series ofaligned cylindrical hollow track sections slotted for the passage of adoor-hanger, a supporting bracket located at the joint of said tracksections and formed of separate sections adapted to clamp said tracksections between them, a fastening device on the rear yone of saidbracket sections, and means comprising interlocking portions whichinterlock said track sections with said bracket sections againstrelative rotation of said track sections upon the assembling of saidbracket sections and said track sections, said interlocking portionsclosely fitting each other and so disposed as to intertit in therelative movement of said bracket sections into clamping position.

6. In a sectional door-hanger track, the combination of a series ofaligned cylindrical hollow track sections slotted for the passage of adoor-hanger, a supporting bracket 1o- 5 cated at the joint of said tracksections and formed of separate sections adapted to clamp said tracksections between them, a fastening device on the rear one of saidbracket sections and extending forwardly 10 thereof for securing saidbracket sections together, and means interlocking said track sectionswith said bracket sections upon the assembling of said bracket sectionsand track sections comprising a recess in the outer one of said'bracketsections and a projection on said track sections adapted to closely itin said recess, the Walls of said recess being substantially parallelwith the longitudinal axis of said fastenin device.
